There are 5 multiples of 20 between 1 and 100.
20, 40, 60, 80, 100, 120, 140, 160, 180, 200, 220, 240, 260, 280, 300, 320, 340, 360, 380, 400, 420, 440, 460, 480, 500, 520, 540, 560, 580, 600, 620, 640, 660, 680, 700, 720, 740, 760, 780, 800, 820, 840, 860, 880, 900, 920, 940, 960, 980, 1000
That is 50 multiples of 20 below 1,000, ending at 1,000.
Factors are the mirror image of multiples: they divide into 20 exactly, rather than being built from it. The factors of 20 are 1, 2, 4, 5, 10, 20.
Written as pairs: 1 × 20, 2 × 10, 4 × 5.
Broken all the way down into primes, 20 = 2² × 5.
The lowest common multiple (LCM) of two numbers is the smallest number that appears in both of their multiplication tables. Here is 20 paired with the numbers it is most often compared to.
| Pair | LCM | Greatest common factor | Next common multiple |
|---|---|---|---|
| 20 and 2 | 20 | 2 | 40 |
| 20 and 3 | 60 | 1 | 120 |
| 20 and 4 | 20 | 4 | 40 |
| 20 and 5 | 20 | 5 | 40 |
| 20 and 6 | 60 | 2 | 120 |
Start at 20 and keep adding 20. That gives 20, 40, 60, 80, 100, and the pattern continues for as long as you want to go. Multiplying is simply a shortcut for the same thing: 20 × 7 = 140 saves you counting seven hops one at a time.
A number is divisible by 20 when it ends in 00, 20, 40, 60 or 80.
Because 20 is even, every one of its multiples is even too — you will never find an odd number in this table.
Multiples of 20 always end in 0 or 5, which is why they turn up so often in money and measurement problems.
The multiples of 20 are 20, 40, 60, 80, 100, 120, 140, 160, 180, 200, and so on. Each one is 20 multiplied by a whole number, so the list continues without end.
There are 5 multiples of 20 between 1 and 100: 20, 40, 60, 80, 100.
There are 50 multiples of 20 below 1,000. They run from 20 up to 1,000.
The 10th multiple of 20 is 20 × 10 = 200.
The factors of 20 are 1, 2, 4, 5, 10, 20 — 6 in total. Factors divide into 20; multiples are built out of it.
No. 20 is a composite number — it has 6 factors, and breaks down into 2² × 5.
The lowest common multiple of 20 and 2 is 20. It is the first number that appears in both multiplication tables.
